Dionex IonPac CS16 阳离子交换柱 079805

利用 Thermo Scientific? Dionex? IonPac? CS16 毛细管分析和保护柱测定多种样品基质中浓度差异*的邻近阳离子（如钠离子和铵离子）。 样品基质包括环境水样；使用铵盐、吗啉或乙醇胺处理的发电厂水；化学添加剂；化学加工溶液；洗涤液；电镀槽和工业溶剂。 Dionex IonPac CS16 柱专为用于 Thermo Scientific? Dionex? IonPac? CS15 柱多数应用而设计，因其较大的线性工作范围也*用于此类应用。

描述

在测定差异*的钠离子和铵离子比例时可实现性能

• 专为测定多种样品基质中差异*的邻近洗脱阳离子（如钠离子和铵离子）浓度比例而优化。

• 在存在锂、钠、铵、钾、镁和钙的情况下，测定复杂样品基质中的短链烷基胺和烷醇胺。

• 使用等度酸淋洗液，在少于 20 钟内分离比例zui高达 10,000:1 的钠离子和铵离子。

• 使用梯度甲磺酸 (MSA) 淋洗液分离比例zui高达 20,000:1 的钠离子和铵离子。

• 高容量色谱柱可改善样品装载量和峰分辨率

• 在 40?C 的*操作温度下达到zui大峰效率

• 分析低 pH 值样品的*羧酸盐官能团色谱柱

• 兼容有机溶剂（不包括乙醇），以增强分析物溶解度，优化柱选择性，便于有效的柱清洁

更低的淋洗液要求，降低运行成本

由于使用相同的填料，Dionex IonPac CS16 毛细管柱提供的性能与标准孔和微孔 Dionex IonPac CS16 柱相同。 由于毛细管系统运行的淋洗液流速仅为标准孔系统的 1%，需要的淋洗液更少，产生的废液也更少，从而降低了运行成本。

提供多种规格，实现应用灵活性

• 5x250mm、2x250mm 分析柱

• 5x50mm、2x50mm 保护柱

• 0.5x250mm 毛细管柱、0.5x50mm 毛细管保护柱

• 更长的 250 mm 柱，实现更复杂样品基质的更高分辨率分离

• 更小柱内径提供更高质量灵敏度，节省淋洗液和试剂，从而降低运行成本。

用途和特点：
IonPac CS16是高容量，羧酸功能基的阳离子交换分离柱，用于等度分离浓度比悬殊的Na+和Li+（浓度比可达10，000：1）；以及分析复杂基质中的短碳链烷基胺和烷醇胺。IonPac CS16基本适用于IonPac CS15的分析范围。IonPac CS16柱在40℃时分离效果。有机溶剂可匹配方便清洗柱子。

Dionex IonPac CS16 阳离子交换柱

High-Capacity Carboxylate-Functionalized Column for Disparate Sodium and Ammonium Concentrations

The IonPac^? CS16 is the column of choice for disparate concentration ratios of adjacent eluting cations such as sodium and ammonium in diverse sample matrices. The high-capacity, high-resolution CS16 column can be used for short-chained amines, including alkylamines and alkanolamines, in diverse sample matrices. The CS16 column is now available in capillary format (0.5 × 250 mm) offering reduced eluent consumption and reduced operating costs.

• For disparate concentration ratios of close-eluting cations such as ammonium and sodium in complex matrices

• Ideal for trace-level ammonium in high concentrations of sodium

• Ideal for trace-level sodium in high concentrations of ammonium or amines

• Best carboxylate-functionalized column to tolerate samples with low pH

• Isocratic acid eluent and elevated temperature (40 °C) required for sodium: ammonium ratios to 1:10,000

• Gradient MSA eluent and elevated temperature required for sodium: ammonium ratios up to 1:20,000

• Useful for short-chained amines, including alkylamines and alkanolamines

• Compatible with organic solvents excluding alcohols

Using an isocratic acid eluent and elevated temperature (40 °C) coupled with suppressed conductivity, ratios up to 10,000:1 of sodium and ammonium can be resolved in less than 20 min. Sample matrices include environmental waters; power plant waters treated with ammonium, morpholine or ethanolamine; chemical additives; chemical process solutions; scrubber solutions; plating baths; and industrial solvents. The CS16 is designed for use in most IonPac CS15 applications.

The CS16 column has the highest capacity among Dionex carboxylate-based cation columns, resulting in improved loadability and resolution. Use the CS16 with the Eluent Generator for simplified, consistent methanesulfonic acid eluent preparation. Use the Cation Self-Regenerating Suppressor (CSRS^? 300) with standard or microbore CS16 columns or the Cation Capillary Electrolytic Suppressor (CCES^? 300) with the CS16 capillary column.
